[ISSHA] ANNOUNCEMENT: Reference Standard Saxitoxin is now available

[Henrik Enevoldsen]

ANNOUNCEMENT:

US FDA Reference Standard Saxitoxin is now available from the US National Institute of Standards and Technology (NIST), a bona fide part of the US
Government.  NIST charge for what they distribute, but the charge is strictly to recover costs or a part thereof and there is no profit.

To order, go to the standard reference materials page of the NIST web site

    http://www.nist.gov/ts/msd/srm/

and enter 

    8642

in the 'SRM/RM Number' box, or enter

    saxitoxin

in the 'Keywords' box.

The vials are each 1.2 mL as before, but the unit of issue is now 10 vials.  When the FDA distributed SSTX directly it was sent out in units of 3 vials.  The charge listed for a NIST unit of 10 vials is $361.

Comparisons of this lot (Lot 089) with the previous lot of SSTX (Lot 088) indicate that they have the same concentration.  However, the standard is now packaged with the intent that it be diluted by mass, instead of by volume.  Follow the instructions included with the standard.
